PATRICK TOOHEY, OF DARRAGH, PENNSYLVANIA.

WRENCH.

SPECIFICATION forming part of- Letters Patent No. 751,821, dated February 9, 1904,

Application filed January 20, 1903.

To all whmn it may concern:

Be it known that I, PATRICK TooHEY, a citizen of the United States of America, residing at Darragh,in the county of Westmoreland and State of Pennsylvania, have invented certain new and useful Improvements in \Vrenches, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in wrenches, the main object of the invention being to provide a quick-acting wrench, such as is generally known as the monkey-wrench type.

The invention, briefly described, comprises a toothed shank carrying a rigid or stationary jaw and a slidable jaw mounted on the toothed shank. This slidable jaw comprises two membersnamely, the casing member and the jaw member, comprising a block which is shouldered to fit in the casing member and has a toothed underneath face which is normally held in engagement with the toothed face of the shank by means of a spring riveted to the back of the casing member and having its ends engaging the back of the toothed shank. This construction will be hereinafter more fully described and then particularly pointed out in the claim, and in describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, and wherein like numerals of reference indicate like parts throughout the several views, in which Figure 1 is a detail plan view of my improved wrench. Fig.-.2 is a central longitudinal sectional View thereof. Fig. 3 is a detail perspective view of the jaw member of the sliding jaw. Fig. 4 is a cross-sectional view through the sliding jaw of the wrench.

To put my invention into practice, I provide a toothed shank 1, which carries at one end a suitable handle 2 and at its other end is provided with an integral rigid jaw 3. I also provide the slidable jaw, which comprises the Serial No. 139,746. (No model.)

casing member 4, which embraces the shank 1 of the wrench and has riveted to its closed end the bow-spring 5, the ends of which abut or engage with the back of the toothed shank 1 for the purpose of holding the teeth 6 of the block 7 normally in engagement with the teeth of the shank 1. This block 7, forming a part of the sliding jaw, is provided with shoulders 8, which rest against the edges of the casing, as seen in Fig. i, the reduced toothed portion of the block lying within the casing and the remaining portion of the block extending beyond the casing. The block is secured in the casing by means of rivets or dowel-pins 9 inserted through the casing and through the reduced portion of the block. In order to adjust the sliding jaw, the thumb is placed on the back of the casing 4 and pressure brought to bear against the same, which compresses the spring 5 and forces the teeth 6 away from the teeth of the shank. As soon as the pressure is relieved the tension of the spring again draws the teeth of the block into engagement with the shank.

It will be observed that the slidable jaw can be readily and quickly moved along the shank, whereby the quick adjustment of the wrench may be obtained.

It will be noted that various changes may be made in the details of construction without departing from the general spirit of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

In combination with the shank provided on one of its faces with ratchet-teeth, and the fixed jaw on the shank, of a movable jaw comprising a block provided with teeth, throughout its entire face, said'block on its sides being cut away to substantially'the width of said shank, shoulders formed by said cutaway portions, a casing of U shape having its sides embracing the shank sides and having its lower edges abutting against sald shoulders, means for securing said sides of the easing to the sides of the movable jaw formed by said cut-away portions; and a bow-shaped spring arranged -in said casing and bearing against the rear face of the shank, the ends of said spring extending Within said casing, said movable jaW being depressed evenly throughout the length thereof, to bring all of the teeth thereof out of engagement with the shank-teeth. 10

In testimony whereof I afiix my signature in the presence of two Witnesses.

PATRICK TOOHEY. Witnesses:
